X-ray powder diffraction (XRD), inductively coupled plasma (ICP), atomic absorption (AA), Mössbauer, scanning electron microscopy (SEM/EDS), Raman and thermogravimetry (TG) analyses indicated that the Fe oxide present in the IOTs (sandy tailing (ST) and mud tailings (MT), can be reduced with H2 at 500 ºC to produce α-Fe. Upon magnetic separation the mud tailing produced a 77 wt.% magnetic fraction increasing the Fe content from 19.2 to ca. 56 wt.% of Fe. On the other hand, the sandy tailing resulted in a 15 wt.% magnetic fraction increasing the Fe content from 19.2 to 70 wt.%. These results indicate that up to 86% of iron can be recovered from the IOT wastes already in the metallic form which can be very interesting for the steel industry.engUniversidade Federal de Minas GeraisUFMGBrasilICX - DEPARTAMENTO DE QUÍMICAJournal of the Brazilian Chemical SocietyHidrogênioRefugos (Metalurgia)Redução de minériosFerro - Minas e mineraçãoResíduos - ReaproveitamentoHydrogenIron ore tailingIronMagnetic separationRecoveryReductionIron recovery from iron ore tailings by direct hydrogen reduction at low temperature and magnetic separationinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://jbcs.sbq.org.br/default.asp?ed=329Rochel Montero LagoAna Paula de Carvalho TeixeiraPaula Sevenini PintoJosé Domingos ArdissonAdriana Barbosa SalvianoLuisa Emanuele MilagreLarissa Caroline Martins MoreiraHamilton Pereira da Rocha JúniorFabrício Vilela Parreiraapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/61007/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALIron Recovery from Iron Ore Tailings by Direct Hydrogen Reduction at Low.pdfIron Recovery from Iron Ore Tailings by Direct Hydrogen Reduction at Low.pdfapplication/pdf3017732https://repositorio.ufmg.br/bitstream/1843/61007/2/Iron%20Recovery%20from%20Iron%20Ore%20Tailings%20by%20Direct%20Hydrogen%20Reduction%20at%20Low.pdf8b785646ab68e0c0fc3378bb2da23d81MD521843/610072023-11-16 14:18:19.281oai:repositorio.ufmg.br:1843/61007Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-11-16T17:18:19Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
